HomeRAB Pre-Cladding
Description

HomeRAB Pre-Cladding is a cost-effective robust rigid air barrier offering resistance to gusting winds to reduce draught and keep homes warm creating comfort inside. Each panel is engineered with a green water repellent sealer to keep moisture out, ensuring the panel remains dry.

The structural stability of fibre cement creates the strength and protection needed for meeting the bracing requirements of Very High wind zones, making it the perfect solution for residential buildings. James Hardie guarantee superior performance and peace of mind.

Rigid air barriers by James Hardie work by equalising the air pressure within the external wall cavity, making the building airtight providing superior weather-tightness, structural bracing and fire protection, whereas traditional flexible wall underlay can struggle to perform in these conditions.

HomeRAB Pre-Cladding is suitable for the exterior of almost all residential buildings including those in Very High wind zones. It is fixed directly to the framing and then vertical joints are sealed over the face.

HomeRAB Pre-Cladding is suitable for use behind all James Hardie claddings or alternative claddings such as brick, timber weatherboard and more.
